PLANING OR IVIITERING TABLE.

SPECIFICATION forming' part of Letters Patent No. 788,436, dated April25, 1905.

Application tiled February 5, 1904. Serial No. 192.116. i

T0 all Ivi/m71?, it 711,01/ concern:

Be it known that I, LOUIS R. SLEvIN, a citizen of the United States,residing in the city of St. Louis, in the State of Missouri, haveinvented certain new and useful Improvements in Planing or MiteringTables, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming part of thisspeciiication.

My invention relates to a table for holding boards or other pieces ofWood in a fixed position while being planed or Initered and forfurnishing level bench-jaws on which a cutting implement operates duringits action on the object held by the table.

The invention consists in features of novi elty hereinafter fullydescribed, and pointed out in the claims.

Figure I is a perspective view of Iny planing-table. Fig. II is anenlarged horizontal section taken through one end of the table on lineII II, Fig. I. Fig. III is an enlarged vertical section through thebench-jaws of the table.

1 designates a pair of end bases that are united by ties 2 and eachsurmounted by a pair of standards 3.

4 designates pairs of uprights that are swingingly connectedintermediate of their ends to the upper ends of the standards 3 bypivot-bolts 5. The upper ends of each pair of uprights 4 are pivotallyand swingingly united by cross-ties 6, secured thereto.

7 designates a pair of bench-jaws, one of which is secured to the upperends of the uprights 4 at one side of the planing or Initering table andthe other of which is secured to the uprights at the other side of saidtable. The bench-jaws 7 have absolutely plane upper faces to receiveaplane or other cutting implement that is operated thereon. Each of thebench-jaws is of angle shape in cross-section, and the horizontal wingofeach furnishes the plane upper surfaces, while the vertical wing of eachjaw extends downwardly,whereby the two vertical wings of the jaws occupypositions parallel with each other to receive a board or other articleto be operated upon placed between the jaws, as indicated at A, Fig.III.

8 designates ties connecting the standards 3, and 9 designates tiesconnecting the up-l rights 4 at one end of the table with the uprightsat the other end.

The uprights 4 being pivoted to the standards 3 in pairs are arranged topartake of parallel swinging movement at each end of the table andduring such movement carry therewith the bench-jaws 7, so that said jawsare maintained in approximately the same parallel dispositions withrelation to'each other when the uprights are swung in either direction.The swinging of the uprights is accomplished by the following means: 10designates bracket-ties pivotally and swingingly connecting the lowerends of one pair of the uprights at each end of the table and providedwith arms 1l, that contain sockets 12. (See Fig. II.) 13 designatesbrackets secured to the other pairs of the uprights 4 opposite to thebrackets 10, each of these brackets 13 being provided with an arm 14,containing a threaded aperture positioned in alinement with the sockets12 in the bracket-arms 11. 15 designates screw-rods provided at theirouter ends with handles 16 and having screw-threaded inner portions 17that operate in the screw-threaded apertures of the bracket-arms 14 andthe ends of which ter- Ininate in the bracket-arm sockets 12, in whichthey are loosely seated, as seen in Fig. II. I/Vhen the screw-rods 15are rotated, the screw-threaded portions thereof by operating in thethreaded arms of the brackets 13 and in the sockets of the bracket-arms11 cause movement of said bracket-arms away from each other, and as aconsequence the lower ends of the uprights 4 are moved correspondinglyto cause the bench-jaws at the upper ends of the uprights to approacheach other to clamp the article placed between said jaws.

18 designates guides projecting from the sides of the braces 1, and 19designates equaliZing-links arranged in pairs at each end of the tableand each pivoted at one end to one of the uprights 4 of each pair ofuprights. The lower ends of these links are connected by slide-pins 20,that operate in the guides 18 when the pairs of uprights are swung inthe manner mentioned. These equaliZing-links by their connection to theuprights and having the riding engagement provided by the slide-pinsserve to direct the movement of the uprights and maintain them in thesame relative positions at all times. It will be seen that when thelower end of one pair of the uprights is swun inwardly the link 19,connected thereto, wi l be thrown downwardly to carry the other link ina like direction and swing the second pair of uprights in a directioncorresponding to that of the iirst pair of uprights. When either pair ofuprights is swung in the opposite directions, a reverse movement isimparted to the links and second pair of uprights.

21 designates upright scale-bars secured to the table at each endthereof.

22 designates slides loosely iitted to the scale-bars 21 and adapted tobeheld at any desired elevation on said bars by set-screws 23.

24 designates rest-blocks carried by the slides 22 and by which thearticle held between the bench-jaws 7 may be adjusted and upheldprevious to being clamped between the bench-jaws to be operated upon.The rest-blocks 24 are loosely applied to the slides 22, and verticaladjustment thereof is provided through the medium of adjustment-screws25, passing through the slides and entering into the rest-blocks. Bythis construction the piece of work to be operated upon-,as, forinstance, a piece of board-may be readily adjusted vertically to thedesired position at each end of the table, so as to acquire the properpositioning thereof before the article is clamped and work is begunthereupon.

In the use of my table the article to be planed or mitered is readilyand quickly clamped between the bench-jaws subsequent to its beingplaced therebetween and adjusted to the desired position, and the uppersurfaces of the bench-jaws being absolutely plane furnish workingsurfaces on which the cutting implement may be operated with thegreatest degree of accuracy until the face of the article upon which theo erator is working is brought to the desired inish.

l claim as my invention- 1. In a planing or mitering table, thecombination of a pair of bench-jaws provided with plane top surfaces,and means whereby said bench-jaws are rockingly supported to maintaintheir clamping-faces and top surfaces in unchanging parallel planes,substantially as set forth. Y

2. In a planing or mitering table, the combination of two sets ofswingingly-mounted uprights, bench-jaws at the upper ends of saiduprights, means for swinging said uprights to impart movement to thebenchjaws, jaw-supporting means carried by said uprights so connectedthereto as to maintain the clamping and top surfaces of said jawsrespectively in unchanging parallelplanes, and means for maintainingsaid uprights in alinement with each other, substantially as set forth.

3. In a planing or mitering table, the combination of two sets ofswingingly-mounted uprights arranged in pairs for parallel movement,bench-jaws at the upper ends of said uprights, means for swinging saiduprights, and jaw-supporting means carried by said uprights so connectedthereto as to maintain the clamping and top surfaces of said jawsrespectively in unchanging parallel planes, substantially as set forth.

4. In a planing or mitering table, the combination of two sets ofswingingly-mounted uprights arranged in pairs, bench-jaws at the upperends of said uprights, bearings carried by said uprights, screw-rodsoperating in said bearings to secure said uprights, and jawsupportingmeans carried by said uprights so connected thereto as to maintain theclamping and top surfaces of said jaws respectively in unchangingparallel planes, substantially as set forth.

5. In a planing or mitering table, the combination of two sets ofswingingly-mounted uprights, bench-jaws at the upper ends of saiduprights, and equaliZing-links for controlling said uprights,substantially as set forth.

6. In a planing or mitering table, the combination of a base, two setsof swinginglymounted uprights pivoted to said base, benchjaws at theupper ends of said uprights, means for swinging said uprights,equalizing-links connected to said uprights, guides projecting from saidbase, and slide-pins carried by said links and operating in said guides,substantially as set forth.
